Looks normal.
It shows that you are running on the intel by default, and using the nvidia when you use prime-run.

I have noticed that with the same proprietary drivers on distributions like EndevourOS (another Arch), Nobara (Fedora), and especially RegataOS (OpenSuse), the session with Wayland worked perfectly on an external monitor

Are they actually the same?
You installed ‘prime’ things and configured your system to work that way?
Or did you just install the nvidia drivers?

@sier0

Where do you think the problem lies?

As explained above.
You have a hybrid system, with the iGPU used by default. But you are plugging the monitor into the dGPU. Or at least thats what I guess, as thats usually the case in these scenarios.

There are multiple approaches to this like here:

Second screen doesn't work with proprietary drivers (Laptop with amd hybrid drivers needed)

Since you’re using an external monitor, you probably want to follow this like I do: NVIDIA Optimus - ArchWiki I have three external monitors connected to my hybrid Intel + NVIDIA laptop: DP, HDMI & Thunderbolt 4. The former two are connected to the discrete NVIDIA card and the latter are connected to the integrated Intel GPU. I created a split package for all use cases based on the aformentioned Arch wiki article. You can try it out if you’d like by following my README, install it and reboot a…

And envycontrol, etc. But you stated you did not want to set it to ‘nvidia-only’

@sier0

most of these have led to a solution that is not what I am looking for, to switch only in nvidia mode.

So you either want reverse-prime or something similar
